' METALLIC BARREL.

Specification` of Letters Patent.

Patented Aug. 9, 1910..

Application filed August 1, 1906. Serial No. 328,652.

Cleveland, in the county of Cuyahoga andy State of Ohio, have invented a certa-1n new and useful Improvement. in Metallic Barrels, of which the following is a full, clear, and exact description.

The'object of the present invention is to provide means for securing together the sections of a metallic barrel.

It is particularly desi v ed to eiect the s'ecuring together of barre sections by metallic rings which ymay be cheaply made and easily applied, and which are, by \reason of their particular construction, capable of securing a liquid-tight connection. Other advantages such as permitting an increased length ofV barrel of cheap construction and providing -a rolling surface and. tilting bearing will appear from the more detailed description to follow.

In the accompanying drawing, Figure l is a side'ele'vation partly broken away, showing an embodiment of my invention. Fig. 2 is a vertical section of one of the barrel ends. Fig-3 is a detail section showing a modification of securing band and .also showing a modified form of packing ring,-the dotted lines indicating the position of the band when permanently applied. Fig. 4 is a detail sectional view showing the securing band of the form illustrated in Fig. l before it is secured in position,-the spacing ring shown inFig. 1 being omitted. F i0. 5 is a detail section showing the form 0I securing band illustrated in Fig. 3, with the spacing ring omitted. Fig. 6 is a fragmentary perspective view showing the form of band illustrated in section in Figs. 3 and 5.

In carrying out my invention, .I provide the sheet metal barrel sectionsA with circumferential flanges A around their inner edges. These anges may abut, as shown in Figs. 4 and 5,. or they may be separated by a spacing ring B as shown in Figs. l and 3. This spacing ring may be of any suitable material, and is designed more particularly to serve the purpose of increasing the length of the barrels without involving any increase in the expense or diiiculty of making deeper sheet metal sections,which. sections 4'are drawn by a process the difficulty and expense of which are greatly increased by an increased depth. Further, this spacing ring may be utilized for carrying the bung.

The securing band C, by which I hold the sections together whether thev spacing ring be used or not, is provided during its manufacture with an inwardly turned flange C on one side, of proper dimension to secure a close t against the peripheral flange of one The other side or of the barrel sections. edge of the `band C may also be provided with an inwardly directed flange C2, as shown in Figs. l and 4 for the purpose of embracing the peripheral flange on the other barrel section. When I provideI the band with this second ange C2, it is,.of course, necessary to have the edge bent backward or outward, as shown in Fig. 4, to such an extent as to enable the band to be slipped into position, after which the backward or outwardly bent edge is bent inward under heavy hydraulic pressure so that the flange thereon embraces and irmly holds the flange of the second barrel section. I have discoveredthat in order to properly bend the band together, it is necessary to kerl. the edge having the flange C2, as shown in Fig. 1.

By having the edge ofthe band kerfed as shown, the metal on. beingpressed inward and crowded so as to draw the barrel sections together, may be evenly pressed without buckling or breaking so as to form an absolutely liquid-tight joint. I have found that when .a solid, continuous, metallic ring ".is bent or crowded in this manner, it is impossible to obtain a close engagement between it and the surface' of the adjacent barrel ange or packmg ring, since the metal bulges and buckles in spots. In order to' prevent the possibility of leakage through these kerfs after the kerfed edge of the band .is bent to its permanent position, I preferably provide a packing ring D designed to fit against the peripheral flange on the barrel section and to extend under the kerfs so that these kerfs shall not bel continuous with the joints between metallic section-s, thus avoiding the possibility of leakage through the joints and kerfs. This packing ring is', in some instances, provided with a groove along the side to permit it to give somewhat more readily underneath the powerful compression which is applied-'to the metallic flange and permit it to'crowd into the corners of the space which it occupies.

In theforin of band which I have illustrated in Figs. 3, 5 and 6 I providethe band with but one flange C during the process of manufacture and kerf the other edge CEx which is extended so that it may be bent inward when applied to the barrel. As this edge C is bent inward, the fingers formed by the kerfs, crowd together and ,draw the flanges of the b arrelsections 4closely up against the abutting surface of the flange of the other barrel section or against the spacing ring B, when such ring is used, and these fingers will, by reason of the kerfs, be

crowded into close engagement withoutbuckling or breaking of the metal, thus creating a tight waterproof joint. When either foi-iii of band is used it is,obvious that the` spacing ring may-be used equally well in either case.

By i'eason'of the securing band having a broad, outer surface, it -isv possible to make the bari'elof the ordinary shape tapered at both endsv and yet provide it witha rolling surface such as is frequently attained in wooden barrels by the use of `two hoops placed close to the center. This is of the greatest advantage in handling heavy materials for which lsuch barrels are used. Further, the broad, fiat band applied in this manner to barrels with tapered ends, provides a tilting bearing whereby the barrel may be easily turned over on one end.

The advantages of manufacture and mode inthe art, and it is'not thought necessary to recite them in detail. -It is further obvious that certain modifications in structure may be made without departing fromthe spirit of my invention, and I desire to in clude these within the scope of my claims.

Having thus described my invention, I claim: n

1.,In a barrel, a pair of sections having outwardly extending flanges, an annular band having an inwardly extending flange alongone edge fitted against the flange of one of the barrel sections, the other edge of the band being bent in against the flan e of .the other barrel section and kerfed at s ort intervals to such an extent as to be capable. -.of bending inward without buckling.

2. In a barrel, a pair'of'sections having circumferential flanges at their proximate ends, an annular band having a flange along one edge fitted to the flange on one of the barrel sections, said band extended over and 3. In a barrel2 a pair of sections separated by a spacing ring, circumferential fianges on the ends of the sections which are adjacent to the spacing ring, a broad securing band extending across the spacing ring and overlapping the 4circumferential flanges on the barrel sections and having vside flanges which hold the barrel sections together, said band having a substantially flat outer rolling siirfaceaii'd havingone of its edges'v keifed. In testimony whereof, I hereunto affix my signature in the presence of two witnesses. of applicationY are'obvious togthose skilled HENRY w. AVERY.
